My Dixie is the exact same way. I worked on reinforcing a really good come with her and instead of my voice I use a whistle. She knows when she hears the whistle she has to come or she would be reeled in on the long line. Of course when I have her out now she is not on the line but she is conditioned that when she hears the whistle to come.

It's interesting to see the turmoil in her eyes, should I go to mom or continue going after the bunny. Usually mom wins but not always!
